Supported ruthenium was used in the liquid phase catalytic transfer hydrogenation of furfural. To improve the stability of Ru against leaching, phosphorous was introduced on a Ru/Al2O3 based catalyst upon impregnation with ammonium hypophosphite followed b ...

The first examples of (arene)Os(II) curcuminoid derivatives have been prepared and characterized. The neutral complexes [(p-cym)Os(curc)Cl] (1) and [( p-cym)Os(bdcurc)Cl] ( 2), together with the cationic derivatives [( p-cym)Os(curc)(PTA)][SO3CF3] (3) and ...

The synthesis of five half sandwich ruthenium(II) trichlorogermyl complexes of the type [(η6-Arene)Ru(PR3)Cl(GeCl3)] (PR3 = Phosphane and phosphite ligands; Arene = p-cymene or C6H5-OC2H4OH) is reported: [(η6-p-cymene)Ru(P(OMe)3)Cl(GeCl3)] (1), [(η6-p-cyme ...

Two heterobimetallic mu-dppm bridged Fe,Ru complexes, [(eta(6)-Arene)RuCl2(mu-dppm)Fe(CO)I(eta(5)-C5H5)] (Ar - C6H6 (1) and p-cymene (2), dppm-1,1-bis(diphenylphosphino)methane) were obtained in a facile reaction between [Fe(eta(5)-C5H5)I(CO)(kappa(1)-dppm ...

Designing compounds that bind to the acidic patch of the nucleosome core particle (NCP) is an emerging therapeutic approach that can inhibit the binding of key chromatin factors. Pretreatment of human ovarian carcinoma, A2780, cells with RAPTA-T, an antime ...

A series of neutral ruthenium(II)-arene complexes, [(arene) Ru(Q(R))Cl] (arene = p-cymene or hexamethylbenzene), containing 4-acyl-5-pyrazolonate (Q(R)) ligands with aromatic substituents in the acyl moiety (a phenyl in Q(Ph) and a 1-naphthyl in Q(naph)) a ...

A series of organotin(IV) derivatives R3SnL (1-3), R2SnLCl (4-6) and R2SnL2 (7-9) (where R = Me, Bu, Ph and L = 4-(benzo[d][1,3]dioxol-5-ylmethyl)piperazine-1-carbodithioate) were prepared from the reaction of 4-(benzo[d][1,3]dioxol-5-ylmethyl)piperazine-1 ...

The reactions of Pt-3n(CO)(6n) (n = 2-5) homoleptic Chini-type clusters with increasing amounts of 1,3,5-triaza-7-phosphaadamantane (PTA) result in the stepwise substitution of one terminal CO ligand per Pt-3 triangular unit up to the formation of [P ...

Exploiting additional degrees of freedom in solid-state materials may be the most-promising solution when approaching the quantum limit of Moore's law for the conventional electronic industry. Recently discovered topologically nontrivial spin textures, sky ...

Ruthenium-based compounds show strong potential as anti-cancer drugs and are being investigated as alternatives to other well-established metal-based chemotherapeutics. The organometallic compound [Ru(eta(6)-p-cymene) Cl-2(pta)], where pta = 1,3,5-triaza-7 ...
